SHUTTLE-BINDER SPRING.

SPECIFICATION forming part of Letters Patent No. 608,038, dated J u1y26, 1898.

Application filed January 4, 1897. Serial No. 617,868. (No model.)

To all whom it may concern:

Be it known that I, ALBERT A. GORDON, of WVorcester, county of Worcester, State of Massachusetts, have invented an Improvement in Shuttle-Binder Springs, of which the following description, in connection with the accompanying drawings, is a specification,

like letters on the drawings representing like parts.

In looms as now commonly made the binder which acts on the shuttle in the box is acted upon by a strong fiat spring. These springs are comparatively heavy, and when applied to a shifting shuttle box their aggregate weight adds considerably to the momentum of the lay, and, further, these springs have frequently to be bent or changed in shape to adapt them to their work, so that they shall exert the desired pressure 011 the binder, and they frequently break transversely because of the strain put on them in use.

This invention has for its object to overcome the objections above stated, and to do this I have deviseda new binder-spring, it

consisting of wire bent to present two arms lying side by side, said new spring being very light and practically indestructible.

Figure 1 shows part of a shuttle-box pro-- senting one cell with a binder acted upon by my novel spring; Fig. 2, a view of the shuttle-box turned over from its position Fig. 1. Fig. 3 shows the spring enlarged and detached. Fig. 4 shows the spring-holder detached, and Figs. 5 and 6 show modified forms of springs.

The metallic shuttle-box frame A, shown as a one-shell box, and its binder a, pivoted at a, are and may be of any usualconstruction commonly used in looms.

Instead of the usual fiat steel spring bent and having a hole for the reception of a screw to confine the spring to the shuttle-box I have produced a novel spring B, it being shown as composed of wire, I having ascertained by practice that a wire spring will stand up to its work and wear longer without breaking than the usual flat steel spring. This new spring is made by bending a piece of strong spring tempered wire to leave two corresponding branches b, somewhat inclined with relation each .to the other, the said pieces 12 of such shape as to prevent the ends of the branches from being drawn from between the lips c.

The end of the wire spring which contacts with the binder may be variously shaped; but Figs. 1 to 3 show a preferred form, wherein the free end of the wire spring is shown bent inwardly, as at e, to make a spring-head which may act against a lump 6 on the binder or between projections. The tailpieces of the branches will preferably rest on a projection f from the shuttle-box, so that by turning the screw 0 in more or less the pressure of the free end of the spring on the binder may be increased or adjusted to the desired amount. This invention is not, however, to be limited to the use of the head e. The double-branched spring acts more readily and favorably than could. a one-branch spring, and the double-branched spring is far more durable than any plate-spring.

In Fig. 5 I have shown a modification wherein the two branches h h have their ends soldered together at 71 making the head different from that shown in Fig; 3, the holder 0 restingon the neck portion 71 In Fig. 6 I have shown another modification, wherein the wire comprising the acting end or head of the spring is flattened to act on the binder, the free extremities of the two branches having'the two necks b and pointed ends b to enter holes in the shuttle-box.

I have herein shown a metallic shuttle-box; but it will be understood that my improved spring may be used on any plain loom having one shuttle-box at theend of the lay and the spring may act 011 the usual binder. The wire used may be either round or of any other usual shape in cross-section.

Having described my invention, what I 5 the said spring presenting two branches, and

means to confine said spring on the shuttle boX, substantially as described.

2. Ashuttle-boX-binder spring composed of two branches and a head uniting said branches :0 at one end, substantially as described.

3. In a shuttle-box, a shuttle-binder spring composed of two branches, one end of said spring acting on the binder while the opposite end thereof is retained by a holder, combined with a holder having lips, substantially I 5 as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALBERT- A. GORDON.
